Funny because that's the way I've done it with all the girls and I don't use the cheats. Once I was able to start getting blue pills and my hack was high enough I just hacked the implants. Yes I do not have Yvette's phone number yet. Great answer as always @darkhound1.There might be some inconsistencies as well, as you shouldn't be able to hack the phone at all if you do not know her phone number.
